GENERAL DESCRIPTION
The Am29F400B in Known Good Die (KGD) form is a
4 Mbit, 5.0 volt-only Flash memory. AMD defines KGD
as standard product in die form, tested for functionality
and speed. AMD KGD products have the same reliability and quality as AMD products in packaged form.
Am29F400B Features
The Am29F400B is a 4 Mbit, 5.0 volt-only Flash
memory organized as 524,288 bytes or 262,144 words.
The word-wide data (x16) appears on DQ15–DQ0; the
byte-wide (x8) data appears on DQ7–DQ0. This device
is designed to be programmed in-system with the
standard system 5.0 volt VCC supply. A 12.0 V VPP is
not required for write or erase operations. The device
can also be programmed in standard EPROM programmers.
This device is manufactured using AMD’s 0.35 µm
process technology, and offers all the features and benefits of the Am29F400, which was manufactured using
0.5 µm process technology.
To eliminate bus contention the device has separate
chip enable (CE#), write enable (WE#) and output
enable (OE#) controls.
The device requires only a single 5.0 volt power supply for both read and write functions. Internally generated and regulated voltages are provided for the
program and erase operations.
The device is entirely command set compatible with the
JEDEC single-power-supply Flash standard. Commands are written to the command register using
standard microprocessor write timings. Register contents serve as input to an internal state-machine that
controls the erase and programming circuitry. Write
cycles also internally latch addresses and data needed
for the programming and erase operations. Reading
data out of the device is similar to reading from other
Flash or EPROM devices.
Device programming occurs by executing the program
command sequence. This initiates the Embedded
Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies
proper cell margin.
Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase
algorithm—an internal algorithm that automatically
2
preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automatically times the erase
pulse widths and verifies proper cell margin.
The host system can detect whether a program or
erase operation is complete by observing the RY/BY#
pin, or by reading the DQ7 (Data# Polling) and DQ6
(toggle) status bits. After a program or erase cycle has
been completed, the device is ready to read array data
or accept another command.
The sector erase architecture allows memory sectors
to be erased and reprogrammed without affecting the
data contents of other sectors. The device is fully
erased when shipped from the factory.
Hardware data protection measures include a low
VCC detector that automatically inhibits write operations during power transitions. The hardware sector
protection feature disables both program and erase
operations in any combination of the sectors of memory. This can be achieved via programming equipment.
The Erase Suspend feature enables the user to put
erase on hold for any period of time to read data from,
or program data to, any sector that is not selected for
erasure. True background erase can thus be achieved.
The hardware RESET# pin terminates any operation
in progress and resets the internal state machine to
reading array data. The RESET# pin may be tied to the
system reset circuitry. A system reset would thus also
reset the device, enabling the system microprocessor
to read the boot-up firmware from the Flash memory.
The system can place the device into the standby mode.
Power consumption is greatly reduced in this mode.
AMD’s Flash technology combines years of Flash
memory manufacturing experience to produce the
highest levels of quality, reliability and cost effectiveness.
The device electrically erases all bits within a sector
simultaneously via Fowler-Nordheim tunneling. The
data is programmed using hot electron injection.

TERMS AND CONDITIONS OF SALE FOR
AMD NON-VOLATILE MEMORY DIE
All transactions relating to AMD Products under this
agreement shall be subject to AMD’s standard terms
and conditions of sale, or any revisions thereof, which
revisions AMD reserves the right to make at any time
and from time to time. In the event of conflict between
the provisions of AMD’s standard terms and conditions
of sale and this agreement, the terms of this agreement
shall be controlling.
AMD warrants articles of its manufacture against
defective materials or workmanship for a period of
ninety (90) days from date of shipment. This warranty
does not extend beyond AMD’s customer, and does not
extend to die which has been affixed onto a board or
substrate of any kind. The liability of AMD under this
warranty is limited, at AMD’s option, solely to repair or
to replacement with equivalent articles, or to make an
appropriate credit adjustment not to exceed the original
sales price, for articles returned to AMD, provided that:
(a) The Buyer promptly notifies AMD in writing of each
and every defect or nonconformity in any article for
which Buyer wishes to make a warranty claim against
AMD; (b) Buyer obtains authorization from AMD to
return the article; (c) the article is returned to AMD,
transportation charges paid by AMD, F.O.B. AMD’s factory; and (d) AMD’s examination of such article discloses to its satisfaction that such alleged defect or
nonconformity actually exists and was not caused by
negligence, misuse, improper installation, accident or
unauthorized repair or alteration by an entity other than
AMD. The aforementioned provisions do not extend the
original warranty period of any article which has either
been repaired or replaced by AMD.

THIS WARRANTY IS EXPRESSED IN LIEU OF ALL
OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING THE IMPLIED WARRANTY OF FITNESS
FOR A PARTICULAR PURPOSE, THE IMPLIED
WARRANTY OF MERCHANTABILITY AND OF ALL
OTHER OBLIGATIONS OR LIABILITIES ON AMD’S
PART, AND IT NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON TO ASSUME FOR AMD
ANY OTHER LIABILITIES. THE FOREGOING CONSTITUTES THE BUYERS SOLE AND EXCLUSIVE
REMEDY FOR THE FURNISHING OF DEFECTIVE
OR NON CONFORMING ARTICLES AND AMD
SH ALL N OT IN AN Y EVEN T BE LIABLE FOR
DAMAGES BY REASON OF FAILURE OF ANY
PRODUCT TO FUNCTION PROPERLY OR FOR ANY
SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL OR EXEMPLARY DAMAGES, INCLUDING
BUT NOT LIMITED TO, LOSS OF PROFITS, LOSS OF
USE OR COST OF LABOR BY REASON OF THE
FACT THAT SUCH ARTICLES SHALL HAVE BEEN
DEFECTIVE OR NON CONFORMING.
Buyer agrees that it will make no warranty representations to its customers which exceed those given by
AMD to Buyer unless and until Buyer shall agree to
indemnify AMD in writing for any claims which exceed
AMD’s warranty. Buyer assumes all responsibility for
successful die prep, die attach and wire bonding processes. Due to the unprotected nature of the AMD Products which are the subject hereof, AMD assumes no
responsibility for environmental effects on die.
AMD products are not designed or authorized for use
as components in life support appliances, devices or
systems where malfunction of a product can reasonably be expected to result in a personal injury. Buyer’s
use of AMD products for use in life support applications
is at Buyer’s own risk and Buyer agrees to fully indemnify AMD for any damages resulting in such use or sale.
